Even joined my MIDI keyboards to the MIDI network thanks to  Patchbox OS running on a Raspberry Pi with a USB MIDI adapter for the older keyboard (DIN5) and plain USB cables for the newer ones.<\/p>\n\n\n\n<p>But the original idea was making MIDI instruments without cables and gadgets (except for the WiFi dongle) so I got a little back again and made a few tests with multimidicast (ipMIDI).<\/p>\n\n\n\n<p>The Drum Kit works great with MIDI cables&#8230; but extremely bad with ipMIDI when using the Raspberry Pi with Patchbox OS as an ipMIDI gateway. High latency and poor sensibility when using MODEP software generators.<\/p>\n\n\n\n<p>So gave up MODEP and jack and used just a USB MIDI adapter to connect the ipMIDI gateway to the MiDiPLUS miniEngine USB. Much better&#8230; but still some latency.<\/p>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<p>Then&#8230; decided to try Patchbox OS own WiFi hotspot instead of my house access point.
